局部淋巴结转移是结肠直肠癌转移的常见方式。作者通过125例患者的CT影象分析,阐明了盲肠癌、升结肠癌、横结肠癌的淋巴结转移途径。盲肠和升结肠的淋巴主要是回流入结肠上淋巴结和结肠旁淋巴结,其中盲肠的淋巴还可以流入中结肠淋巴结及肠系膜根部的主淋巴结,而肠系膜根部的淋巴结转移可以播散到腹膜后,并且沿着主动脉旁淋 Local lymph node metastasis is a common way of colorectal cancer metastasis. The authors analyzed the lymphatic metastasis pathways of blind, colon, and colon cancers through CT imaging analysis of 125 patients. The lymph nodes of the cecum and ascending colon mainly regurgitate into the upper lymph nodes of the colon and the para-colonic lymph nodes. The cecum lymph can also flow into the mesenteric lymph nodes and the main lymph nodes of the mesentery roots. Lymph node metastasis in the mesenteric roots can spread to the retroperitoneum and along the Next to the aorta
